SPECIFICATION forming part of Letters Patent No. 764,827, dated Julyl 12, 1904.

Appiimiou filed Juiy 23, 1901.

To tu w/tm, t uta/y concern:

Bc it known that I, CHARLEs B. SCHOEN- MEHL, a citizen of the United States, and a resident of Vaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Galvanic Batteries, of which the following is a unavoidably wasted, for the reason that thev lower part of the solution became so Weak and inactive that the lower portion of the copper oxid was notattacked andconsumed. The

foregoing is especially true where very iinev or cheap grades of copper oxid are used.`

Further diflculty has been experienced in connection with depolarizers for the reason that the depolarizer usually comprises vessels having parallel side Walls to which the consumed copper oxid would invariably stick, makingv it dilicult to remove the same when recharging became necessary. vWhile the foregoing objection is overcome to some extent, it is nevertheless apparent in most of the basket or cylindrical forms of depolarizers which are usually suspended from the cover or a bridge.

It is therefore an object of my invention to iirst provide a depolariZer-receptacle which will more thoroughly expose its contents, and consequently insure a complete consummation. Said receptacle is not only largest adjacent toits top end, but also has both an exterior and interior exposed surface adapted to be attacked in a manner to work inward from the outside and outward from the inside, thus insuring complete consumption of the material.

A further object of the invention is to construct a receptacle in such a manner that both its interior and exterior wall shall be tapering or set at an angle other than a right angle to a central line through the basket, so as to insure a solidified mass of material quickly freeing itself from all sides of the receptacle,

'including the rod supporting the same, when the .basket is opened and inverted for that purpose; A

Vith the above objects in view` my invention resides and consists in thenovel construction and combination of parts shown upon theaccompanying drawing, forming a part of this specification, upon which similar letters of reference denote like or corresponding parts, and which drawing illustrates a central vertical cross-section through a popular style of battery containing a negative element constructedin accordance with my invention.

Referring now in detail to the letters of reference marked uponthe drawing, A indicates va jar which may be of any of the preferred or well-known types; B, an annular Zinc suspended therein by means of supporting-wires CC, each of whichV is proivded with insulatingwashers D and nuts E, connecting them with the cover F of the ljar, which latter may be of metal. One of these wires C is provided with a binding-screw G, whereby a circuitwire is attached in the customary way.

The depolarizer shown in the drawing consists of a basket suspended centrally of the cover, having exterior tapering side walls set at an angle other than a right angle to a central line through the basket and likewise a perforated bottom, as illustrated. The cover H of this basket may also be formed of perforated metal, if desired. A central rod l passes through the basket to connect the cover thereto and serves as a medium through which the basket is supported. Attached to this rod is a binding-screw J, whereby a second circuit-wire is connected. Interior of this basket I arrange a cone K, which is placed upon the bottom of the basket, with its largest end downmost and the side walls like those of the basket proper and arranged at an angle other than a right angle to a central line through the basket, but deflected in an opposite direction from the exterior wallsthat is to say, the walls lean inward toward the rod, while those of the basketlean-out. 'This form of construction not only gives a greater body of copper oxid at the top, but locates the entire mass in a sort of annular basket,`whichean conveniently be taken out with the jar-cover IOO I larizer-receptacle having both an exterior and interior perforated side Wall set at an angle other than a right angle to a vertical line passing therethrough.

2. In a battery, the combination With the other parts, of an annular basket for holding a depolarizer having an interior perforated side Wall set at an angle other than a right angle to a vertical line passing therethrough, and forming a central opening in the lower portion of the basket only.

3. In a battery of the class described, the combination of a perforated depolarizer-bas ket having its Walls arranged at an angle other than a right angle to a central line through the basket and a perforated cone centrally located Within said basket forming an annular chamber Within the basket, larger through its bottom than its top.

4. In a battery of the class described, the combination of a depolariZer-receptacle comprising an annular perforated basket broader through the top than the bottom, a central chamber Within the basket having'perforated side Walls and openings through the bottom of the basket to insure access therethrough of the solution.

5. In a battery, the combination with the other parts, of adepolarizer-receptacle having perforated side Walls deiiected outward from the bottom to top, and an interior perforated wall for said basket deliected outward from top to bottom, thus forming an annular compartment, all the side Walls of Which are set at an angle other than a right angle to a central line through the basket.

6. In a battery, the combination With the other parts, of an annular receptacle for holding a depolarizer, a conical chamber within the receptacle having perforated Walls to insure access of the solution therethrough.

7. In a battery, the combination with the other parts, of an annular basket suspended from the cover having both its inner and outcr walls deflected in substantially opposite directions from a vertical line and at angles other than a right angle to a central line passing through the receptacle.

8. In a battery, the combination with the other parts, of a depolariZer-basket, having perforated Walls and a hollow cone-shaped perforated bottom, all substantially as set forth.

9. In a battery, the combination with the other parts, of a receptacle for holding a depolarizer, having each of its side Walls perforated and at least one Wall' which extends under some part of the depolarizer-holding space set at an angle other than a right angle, to a vertical line passing through the said receptacle.
